Dave, Thanks for the interesting links. I am surprised that my image captured all six of the objects they mention in the third link with only 1-minute sub-exposures. It will be fun to try the same object with 20-minute subs, after my flexure issues are solved. It was also interesting to see how many of the little smudges in my image were actually galaxies. I thought the seeing was just soft (which it was) but many of those smudges are supposed to be smudges. I am sure longer subs will resolve them better.

You've barely captured (LOL) a Z=2.15 quasar in your luminance: http://www.sierra-remote.com/Science%20Page.htm http://www.sierra-remote.com/Astrophotography%20Page/NGC3628_z% 202.15_Greg_Morgan.jpg http://www.backyardastronomer.com/ccd-images/NGC3628-Quasars.jpg Not bad peering back 10 billion light years, give or take, during a test run.

Hello All,
I have been working feverishly on my new astrograph and everything is now working well except the flexure issue I mentioned in a previous thread. I finally got a chance to run the scope for about 40 minutes a couple of nights ago, and decided to point it at the Flying Hamburger (NGC3628). Due to flexure, I am limited to 1-minute exposures, so this image is not very deep or well defined, but I can see potential. I thought I would post it for others to enjoy. The new scope has over twice the focal length of my previous scopes. This longer focal length, combined with the small pixel size of the ML8300 camera, make for a pretty large image scale. This is going to be fun! :)
Here is a link to the luminance-only image:

Take a peek!
Cheers,
Tyler
